Allready feel the surge within the first week.Iam only taking one capsule in the morning.I will be 70 on 2/19/2012. Iam waking up with the hardest ,thickest ive ever had in my life.And another thing is we are sleeping better.With these results,WOW i can hardly wait to see more.We use NOW brand a lot.We appreciate the integrity of I-HERB for being there for us .

all kinds of muscle aches and joint aches are gone, been taking the product alongside with spirulina&chlorella for about 3 weeks, i especially been having quite bad back pains for couple years upon waking up. Been sleeping better too, could be because of the ZMA that is included in the testojack, just dont take right after going to bed, it does give slight energy boost.

I had my doubts about the claims of this product but after using it for a couple of weeks all doubts were removed. It is not only effective in the gym but also in the bedroom. I am 41 who feels like he is 14.
